What is Operational Context

Semantic interaction support for internet of things (IoT) resources is a key point of the service construction and delivery for the users. Semantic interoperability between interacted resources provides possibilities for them to understand each other. One of the possible approaches to enrich the semantic interoperability is the ontology modeling. Every resource is described by an ontology. The ontology formally represents knowledge as a set of concepts within a domain, using a shared vocabulary to denote the types, properties, and interrelationships of those concepts. Based on the ontology matching techniques, resource ontologies are matched, and resources operate in accordance with this matching. Context is any information that can be used to characterize the situation of an entity. An entity in the considered case is the resource of IoT environment. It is proposed to use the ontologies to describe the context of resource and take this information for task performing. For the service construction, the coalitions of IoT resources that can jointly provide the needed service for a task performing need to be created.
